Frequently Asked Questions

What is a PSA nitrogen generator?

PSA (Pressure Swing Adsorption) nitrogen generators use carbon molecular sieves to separate nitrogen from compressed air, producing high-purity nitrogen gas on demand.

Do you provide international installation?

Yes, we offer global installation and commissioning services with experienced engineers available for on-site support.

What certifications do your products have?

Our equipment complies with CE, ISO, ASME, and other international standards. Full documentation is provided.

Can you customize equipment?

Absolutely. We specialize in custom-engineered solutions tailored to specific flow, pressure, purity, and space requirements.

What is the lead time for orders?

Standard equipment: 4–8 weeks. Custom systems: 10–16 weeks depending on complexity. We provide detailed project schedules.
